A little over an hour ago, protesters once again poured into Union Square, the halfway point of a “March of the 99%” from Herald Square to Zuccotti Park. A Facebook page described the event as “a call to action and a show of unity” as well as a “March for Jobs and Economic Fairness.” Around 5:20 p.m., around 500 people, many of them affiliated with the U.A.W. (the International Union, United Automobile, Aerospace and Agricultural Implement Workers of America) and other labor unions, arrived at the north side of the park, accompanied by a bagpipe band. As of now, at 6 p.m., almost all protesters have dispersed to Zuccotti Park. We’ll have more from the scene in a bit.

Update | 6:25 p.m. See below for Susan Keyloun’s video footage of protesters entering the park, taken on the corner of Broadway and 17th Street.

Update | 8:30 p.m. Around 6 p.m. tonight, Dana Sherne of The Local spotted a large group protesting recent tuition increases at C.U.N.Y. The march, led by people beating drums and carrying American flags, was accompanied by N.Y.P.D. vehicles as it went eastbound on West 4th Street toward Broadway. Watch the first and second half of the procession as it passed Mercer Street.
